ボデイ。[Scope of Claim for Utility Model Registration] (1) An injection valve that injects fuel into an intake passage installed in the body, a throttle valve installed in the intake passage on the downstream side of the injection valve, and an intake valve. In a throttle body for a fuel injection device having an air valve provided in an intake path upstream of the throttle valve so as to be able to open and close according to the pressure, when the throttle valve opens a certain opening degree or more, A throttle body for a fuel injection device, comprising a forced valve opening mechanism for forcibly opening the air valve in response to the opening degree of the throttle valve. (2) The forced valve opening mechanism includes: a throttle arm fixed to the valve shaft of the throttle valve; an air valve arm rotatably pivotally connected to the valve shaft of the air valve and having an engagement piece; Practical use characterized in that the air valve is provided with an engagement protrusion protruding from the end of the valve shaft so as to be able to engage with the engagement piece, and a link rod that connects the throttle arm and the air valve arm. A throttle body for a fuel injection device according to claim 1 of the patent registration claim.
